I think the proposal from CAA is to remove the requirement, not to remove the equipment.
Therefore, should providers continue to support transmission, users who retain the onboard equipment can use it.
Far as I can see there is no move to take the NDB approach out of IMC training and testing as a result of GPS introduction.
And, it's only in UK airspace. No sign of Europe following suit.
So, lots exchanges about not a lot really.
Unless you won £35m this weekend and are about to order a Columbia 400!
